Abstract
Our aim was to determine parameters of motor evoked potential (MEP) from the tongue in healthy children of different age.
Methods. 40 healthy children (age range from 2 years old to 17 years, 14 females & 26 males) were enrolled. All underwent diagnostic TMS, single-pulse protocol, 150-sm round coil, Neiro-MS-D device. Coil was placed on Fz point, registration was performed by the surface electrode on the middle line of the tongue.
Results. MEPs were registered in all cases, its average latency was 6,29±0,64 ms, average amplitude – 0,76±0,24 µV. There were neither gender differences nor amplitude. Significant age difference (p<0.001) was registered between young children (age 2–5 years) and two older groups on latency.
Conclusion. There is a significant age difference in MEPs’ latency between young children and older group. This may be associated with age elongation of the conductors due to the growth of the nervous system. The obtained normative data can be used as a tool for an objective assessment in children with various pathological speech disorders.
